Deyeuxia turczaninowii var. nenjiangensis S. L. Lu (Acta Biol. Plateau Sin. 2: 19. 1984) has been described from N Heilongjiang and Nei Mongol. It may be the hybrid D. korotkyi × Calamagrostis epigeios. It differs from typical D. korotkyi by its looser panicle, narrower glumes, and longer callus hairs ca. 3/4 as long as the lemma. It is intermediate between the putative parents in these characters.
